Saxifraga plant named ‘SAXZ0013’

ABSTRACT

A new  Saxifraga  plant named ‘SAXZ0013’ particularly distinguished by its red coloured flowers with green leaves on a mounding compact round and well branched plant habit that starts to flower quite late.

Latin name of the genus and species of the plant claimed:Saxifraga×arendsii.

Varietal denomination: ‘SAXZ0013’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Saxifraga, botanically known asSaxifraga×arendsii, and hereinafter referred to by the variety name‘SAXZ0013’.

‘SAXZ0013’ is a product of a planned breeding program. The new cultivar‘SAXZ0013’ has red colored flowers with green leaves on a moundingcompact round and well branched plant habit that starts to flower quitelate.

‘SAXZ0013’ originates from an open hybridization made in a greenhouse inApril 2009 in Enkhuizen, The Netherlands. The female parent was anunpatented, proprietary plant identified as ‘SX015’ with smaller,darkred color that blackens with aging and is later to flower whencompared to ‘SAXZ0013’.

The male parent of ‘SAXZ0013’ is unknown. The resultant seed was sown inAugust 2009 in Enkhuizen, The Netherlands.

‘SAXZ0013’ was selected as one flowering plant within the progeny of thestated cross in March 2010 in a greenhouse in Enkhuizen, TheNetherlands.

The first act of asexual reproduction of ‘SAXZ0013’ was accomplishedwhen vegetative cuttings were propagated from the initial selection inMarch 2010 in a greenhouse in Enkhuizen, The Netherlands.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plantinitiated in June 2010 in Enkhuizen, The Netherlands, and continuingthereafter, has demonstrated that the combination of characteristics asherein disclosed for ‘SAXZ0013’ are firmly fixed and are retainedthrough successive generations of asexual reproduction.

‘SAXZ0013’ has not been observed under all possible environmentalconditions. The phenotype may vary significantly with variations inenvironment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar was applied for in theEuropean Union on Jun. 4, 2015, No. 2015/1164. ‘SAXZ0013’ has not beenmade publicly available prior to the effective filing date of thisapplication, notwithstanding any disclosure that may have been made lessthan one year prior to the effective filing date of this application bythe inventor or another who obtained ‘SAXZ0013’ directly from theinventor.

The following traits have been repeatedly observed and are determined tobe basic characteristics of the new variety. The combination of thesecharacteristics distinguishes this Saxifraga as a new and distinctvariety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawings show typical flower and foliagecharacteristics of ‘SAXZ0013’ with colors being as true as possible withan illustration of this type.

The photographic drawings show in FIG. 1 a flowering plant of the newvariety and in FIG. 2 a close-up of the flowers.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions and measurements were taken in Enkhuizen, TheNetherlands under natural light in March 2015. These plants wereapproximately 36 weeks old and were growing in 11 cm pots in polycovered tunnels outdoors. The plants used for the photographs were about36 weeks old growing in Enkhuizen, The Netherlands and the photographswere taken in March 2015.
